GRAND RAPIDS, MI -- A Cedar Springs student who claims she had sex with a teacher had no reason to lie about it, prosecutors said.

"This was not some little student trying to get a teacher in trouble," Kent County Assistant Prosecutor Helen Brinkman said Friday, Nov. 9.

Brinkman made the statement during closing arguments today in the trial for former Cedar Springs teacher Jon Jungkind. He is charged with third-degree criminal sexual conduct involving a student.

Jungkind's attorney, Fil Iorio, has suggested that the 17-year-old student lied about having sex with Jungkind and getting pregnant.

Iorio today suggested the student told a "white lie" to an estranged girlfriend as a way to begin communication once again with the girlfriend. He said the lie then likely grew out of control until it reached school administrators and police.

"(The student) couldn't back out of it and she didn't," Iorio said.

But prosecutors say there is too much evidence to support the student's story. She graduated earlier this year and is now in college.

Jungkind stopped teaching at Cedar Springs in November 2011 and was dismissed in March after withdrawing an appeal with the state teacher tenure board.

Brinkman said the student never approached school officials or police with the sex allegations and did not want it revealed. Jungkind, she said, took advantage of the teen's crush on him.

"She's a moon-eyed kid who was looking at this long-haired science teacher and it was all so cool."

Both Jungkind and the teen have testified that he bought her abortion pills over the Internet, although Jungkind testified he did it simply to help out a good friend in trouble. He has denied every having sex with the teen and said he ended up throwing the pills out after the teen refused to tell her parents about the pregnancy.

The pills cost $226, including tax.

Brinkman said it makes no sense that he threw out the pills.

"He bought it to give to her because it's his kid," she said.

But Iorio said the teen's story is "rife with inconsistencies," including the number of alleged sexual encounters that happened.

The teen initially denied having sex with Jungkind to police and the high school principal, then later said it happened once. During a January court hearing, she claimed two sexual encounters, then this week said it was several times.
